today I have encountered a person, named Stanimir several times who was misbehaving and acting very rude.
For several games he was:
-very rude and annoying
-stopping the game intentionally dozens of times
-after he died he stalked and told what others have and what strategy they use
-he was threatening people several times
-using inappropriate racial jokes
After the bot muted him for spamming he left the game since he was defeated and can't cause any harm.
His name again is Stanimir, I hope you can see the image included.
